JVM timing problem
Hello,
we encounter a time synchronisation problem with the call System.currentTimeMillis(). My guess is, that it has to do with the virtual enviroments (HP/UX machine, with a couple of virtual oracle enviroments).
we can see a time difference between different Oracle containers. In a couple of weeks the difference off a timestamp can be 17 seconds . . . one time even -10 seconds.
That's why we made an simple servlet to write a file with the date-time as a filename. The first day we saw that the time difference was a couple of milleseconds, but after the 2nd day we had a time gap off 3 seconds. The 3rd day, 5 seconds .. but the 4th day: 2 seconds gap .. I compare the file name, with the OS time stamp of the modified attribute.
The simple code in the servlet:
Date date = new Date();
bestandsNaam = date.toString();
FileWriter writer = new FileWriter(directory+formatter.format(date)+".txt");
writer.close();
Can someone tell me if this can be a jvm issue (we use the Oracle variant: ojvm)
I hope that someone recognizes this problem.
Thnx in advance
